1995 ATSF SD75M K3LA

This is an original Santa Fe SD75M K3LAR4. It's a tagless narrow font horn from 1995 with flange style back-cap bolts. One interesting thing about these 1995 K horns is that they were delivered without washers on the manifold bolts. The SD75M/I's have a 1" inch pipe/hose that runs up to the horn, causing them to be extremely overblown. This recording however is on a horn rig with a regular 1/2" air line running to it at 125 PSI. Thanks for watching!
